GNSS Positioning

Status and Features
Nowadays, GNSS receivers have scores – and often hundreds – of channels, enabling them to track GPS, Glonass, Galileo and Compass signals simultaneously. The whole workflow from satellite tracking to calculating the coordinates of the position in a preferred reference system can be conducted automatically in real time. The price of GNSS receivers has dropped steadily since the first GPS receivers came onto the commercial market in 1982. In conjunction with the latest product survey results for GNSS receivers (available at www.geo‑, the author puts today’s GNSS status and features in perspective.

Hemisphere GNSS Releases New GNSS RTK Engine

Hemisphere GNSS has announced the launch of Athena, its next-generation GNSS engine. According to the company, the new core engine has been designed to maximise the ability to excel at the rigorous GNSS requirements of multiple market segment customers in machine control, survey and GIS. Athena is developed for application in virtually every environment where high-accuracy GNSS receivers can be used. Hemisphere’s customers have tested and proven Athena’s performance in long baseline, in open-sky environments, under heavy canopy, and in geographic locations experiencing significant scintillation. The company claims the brand-new GNSS RTK engine has one of the most reliably consistent... (read more)

Combining GNSS Positioning Capabilities

Topcon Positioning Systems recently unveiled the IP-S2, a vehicle-mounted, mobile 3D precision mapping and survey system. The IP-S2 combines dual-frequency GNSS signal tracking and positioning and inertial measurement to integrate laser scanning and digital imaging.   Using 3D laser scanners, LIDAR, and/or cameras, the data collected is integrated, time-stamped and geo-referenced. The customer can then quickly and accurately combine LIDAR "point cloud" and digital imaging data to build 3D models of the areas driven. Sensor integration creates unlimited applications for the technology in GIS, construction, agriculture, mapping, and machine control -- all areas where Topcon has market leadership.   With its...

French Surveyors’ GNSS

The French Order of Chartered Surveyors (Ordre des Géomètres Experts) has set itself the objective of completing a GNSS network over the national territory. This network will allow positioning in real time with a precision better than an inch (2.5cm) anywhere within France. About five hundred surveyors, one third of the profession, already support the network. The project will begin during the first quarter of 2005 and the network will be completely rolled out across the entire country by the end of 2005. It will benefit from the labelling of reference stations by the IGN for ensuring their integration into... (read more)
